How about starting the week with a rumor like that?
Yeah, the Japanese site MACBlog reported today that, according to information from Apple's supply chain, the company plans to launch a new color for the iPhones 7/7 Plus, which would join the current offer in silver, gold, rose gold, black matte (matte) and glossy black (jet black). The new? Bright white (jet white).

The website makes it clear that the information may not be correct, that is, it just "threw" the rumor without putting a hand on the fire.
THE MACBlog it has a good history of hits, but it also misses a lot they, for example, said that the iPhone 7/7 Plus would get a new blue color (something that did not materialize).
It would make a lot more sense for Apple to have launched this since the beginning, in September; on the other hand, with smartphone sales falling as a whole, a good strategy is to launch a new color in the middle of the device cycle to rekindle sales.
